Websites for open residency spots?

We have a friend that did not match in the competitive residency they wanted and took a prelim spot. I am trying to help find all the possible sites that open spots would be posted on. I know of apds.org but do any of you know others that may have useful info?

Thanks!

Maybe nrmp.org?

Some specialties have specific websites. I don't know them all but for urology, I think urologymatch [dot] com has job openings.

What type of residency are they looking for. There is info. on the ACOG site under the clearinghouse section I believe. But that is only helpful if OB/GYN is the goal
